Abstract (en)
[origin: WO2021219383A1] The invention relates to a device for estimating a channel for a communication system, which comprises: - a construction module (10) designed to construct, on the basis of a physical model, a set of vectors (e(θ)) associated with a plurality of values of at least one parameter; - an initialisation module (12) designed to initialise, as a function of the constructed vectors (e(θ)), columns of weighting coefficients defining at least a part of an artificial neural network (20); - an application module (14) designed to apply, as an input to said part of the artificial neural network (20), a vector (x) determined as a function of noisy values so as to produce as an output a vector (ĥ) comprising estimated values; - a module for updating (16) the weighting coefficients of said part of the artificial neural network (20) by means of a learning technique. An associated method and computer program are also described.
